Be it known that I,- "ED'WIN VVATER URY, a

"citizen? ofithe United States, residing at Caldwell, in the county ofEssexand State vv1'5 (Sf-New Jersey, have "invented certain ne and--useful: *Iin rovements 1n; Electric" 1 Switches, of-fwhic thefollowingis aspecificationJ i clectricswitch and seeks,-as one of-its principalobjects,-to" provide a device of this fcharacteri wherein the-breakingof the circuit fthrough the switch will berendered more' safe and surethan heretofore by the i15 use T a -jmember fofliinsulating materi'alwhich niay -be proj ected between cooperat .iing contacts "of the-switchfor separating said contactsj and insulating] the contacts F withrespectto each'fothen I The'invention hasfas a "further object toprovide. a switch fwhereinb'y employing a contact separating member ofinsulating materiahi'as previously "noted, "an efiicient" switch "of:fewer 2 parts "than heretofore em} 25 :ployed-may beproduc'ed whileit-will also e-posjs'ible to manufactureswitches of a greaterivariety. 3

Y And the invention has a still further obj ect to provide a switchwherein the separat- 3 mg membenwill be automatically; locked at the endof its throw inopposite direc tions for maintaining the switch open orclosed. 7 I

Other and incidental objects will appear hereinafter. I Y I I I i In thedrawings: I -v Figure 1 is a longitudinal sectional view throughmyimprovedswitch, 7 Figure 2'is a sectional View similar to Figurel, butshowingthe switch open. a V

Near one end thereof, the-top wall of thecover'isprovided with a longitudinally directed slot '14 andformed in the coverat opposite sides of said slot are spaced pairs indicated at 15 and 16,respectively. Y are 19 at'thelowerside' of theblock whereby circuitwires maybe readily connected 'to' the base block'andmounted atone endupon the terminal 17 isa longitudinally bowed spring contact 21'normally-engaged at its l8,the head 20 being' provided with a fiat upperface against which the contactrests closing afcirci'iit between theterminals. As will be observed, said contact is provided, With anupwardly directed tip 22. Y I r Fitting between the top wall of'thecover 13 and the base block 10 is aswitch member 23 provided at oppositesides thereof with flanges 24 fitting beneath the flanges 11 of the baseblock slidably connecting the switch member therewith and projectingfromv the switch -member at the base thereof is a forwardly directedwedge shaped separating tongue 25. The switch-member is preferably ofsuitable insulating material so, that the tongue 25 is thus dielectricand formed in the upper end of saidmember is a trans verse recess orslot 26. Mounted upon the member is an operating button or knob 27projecting freely through the slot 14 in the top wall of the. cover andprovided with an oblong base 28 slidably, fitting in there'cess 26.Screwed or otherwise securedv to the base of the knob is a bowed spring29 bearing at its'ends against the bottom wall of said recess pressingthe button upwardly against the .top wall of the cover and formed on theupper side of the base to flank the knob are oppositely disposedV-shaped ribs 30 adapted to fit in the pairs of notches 15 and 16selectively. -Thus,as shown in Figure 1, when the switch is closed,
